A steer-by-wire steering apparatus according to the present invention includes: a reaction force actuator control section that controls an output amount of a reaction force actuator; a steering actuator control section that controls a steering actuator in response to a manipulation of a steering operation input member, the steering actuator steering steered wheels via a steering unit; a deviation recognition section that recognizes a deviation between a manipulation amount of the steering operation input member and a steering amount of the steering unit; and a reaction force actuator output boost section that, when the deviation increases, increases the output amount of the reaction force actuator. Thus, the steering reaction force can be appropriately controlled in correspondence with a response delay in the steering amount of the steering unit with respect to the manipulation amount of the steering operation input member.
